The word DINGUS refers to "Dirty-Dick-Dingus," or "Triple D," the name of a 2nd Class Petty Officer of the Navy onboard VP8, who successfully infected over 32 Thai whores while on deployment. Beware of the Dingus, for breathing in close vicinity of the triple D will surely give you the HIV.

Sally felt the wrath of Dingus last night, and now her cooter is green and rotting.

another word for a spaz.
NOTE: a dingus is NOT a stupid person, because a dingus is someone who can make you laugh by doing stupid THINGS, but they are not stupid people. a stupid person is an idiot. idiot and dingus are different.

Commonly known as the "musician's curse word." Derived by jazz artist Charles Mingus. Whenever he did something idiotic in music, fellow musicians would say, "Damn Mingus!" And eventually, it became a "dingus."
A person who is occasionally a spazz in music.
